Oxygen Compounds of Aluminum, Gallium and Indium

The controlled hydrolysis of aluminum alkyl and aryl compounds yields oligomeric species of the formula (RA10) . They are called alumoxanes. Alkyl substituted alu- 

The first step in the hydrolysis reaction is the formation of the water adduct [Eq. (23)] [69], which subsequently eliminates alkane to yield the hydroxide R2A10H. At elevated temperatures, further alkane elimination is observed with the formation of alkyl-alumoxane [67, 68]. Structurally characterized alumoxanes are listed in 

The average Ga-O distance in the two (MesGaO)3 rings is 191.0 pm while the three Ga-O distances in the //-(MesGaO) units are significantly longer (196.7 pm
